I couldn’t agree more. There are already some papers that systematically study Parquet internals: data types, compression ratios, and distribution characteristics like cardinality. But one aspect I feel is still missing is **a reader-friendly Parquet configuration optimized for high-performance reading**. That’s also how I interpreted your perspective on Parquet and proprietary formats. I can imagine scenarios where lakehouse consumers experience slow reads and instinctively blame the reader implementation, when in fact the bottleneck lies in how the Parquet-file-config was written. Once I wrap up the current query engine work, I’d love to pursue a more systematic study on this topic if possible. -- This is an automated message from the Apache Git Service.
